Phase decomposition is a novel technique that decomposes a composite seismic signal into different phase components, which can improve reservoir characterization. The technique is particularly useful in those areas where thin-bed interference causes the phase of the input seismic response to differ from the phase of the embedded wavelet in the data.

When the International Petroleum Technology Conference comes to Saudi Arabia in February, the technical program will include a significant look at both unconventional oil and gas and conventional tight oil in the Middle East. Those are two different concepts in the region and the distinctions are important. The Middle East holds a large conventional tight oil resource, now emerging as a serious focus for development. With so much recent attention devoted to unconventional resources, conventional tight oil could be considered an overlooked sibling.

Thanks to continuing advances in reservoir characterization, technology and innovative thinking, many oil fields around the globe have “grown larger” in recent decades. John Sneider, president of Sneider Exploration Inc., documented examples of mature field growth 20 years ago and recently revisited the topic to focus on mature giant fields. This updated analysis is detailed in chapter 4 of the new AAPG Memoir 125: “Giant Fields of the Decade: 2010 – 2020.”

The estimated hydrocarbon reserves around the world, when produced, can keep us going for the next several decades. But scientific records and our own experiences are enough evidence that climate change is indeed happening. Addressing it requires energy extraction from non-fossil fuels. One such resource is the natural heat of the Earth, or geothermal energy.

Fault interpretation on seismic data has always been a laborious task, especially for large 3-D seismic volumes. Whereas horizon autopicking has advanced significantly during the past three decades, automated seismic fault interpretation lags behind. Fortunately, recent applications of artificial intelligence (deep learning) processes for identifying faults provide significant promise for the future.

The eastern Great Basin of western Utah has long been known as a high heat flow region containing young volcanic rocks and several producing hydrothermal systems. The Utah FORGE Enhanced Geothermal Systems project seeks to advance technology to extract the heat in the huge volumes of hot rock underground, identified or strongly suspected, that do not currently possess adequate permeability. Resolving the underlying mechanisms that have heated such volumes should not only help characterize the magnitude of an individual resource but also create a pathfinder for discovering other systems, both EGS and hydrothermal.

Seismic inversion for acoustic impedance is widely used in our industry today, mainly due to the ease and accuracy of interpretation of impedance data, but also because it allows an integrated approach to geological interpretation. In a series of three prior articles of Geophysical Corner, the application of the different methods for transformation of stacked, prestack and multicomponent seismic data into impedance data were described. In this month’s column we revisit one of the methods, namely colored inversion, to describe in detail the methodology entailed and its application to a seismic dataset from Denmark.

As geoscientists, we are predisposed to associative thinking. Trained for pattern recognition by our education and experiences, we have learned to recognize familiar elements in a new dataset and integrate those pieces of information into a subsurface geological model. However, this learning system is usually biased and most of the time we are unaware of it. With the increasingly common use of machine learning in our workflows to bolster human interpretation, we must become increasingly aware of our biases, so that they they can be minimized as we train the algorithms. Herein is a case study and bias discussion from the Ceará Basin in Brazil, where deep convolutional neural networks are used to aid in the petrophysical analysis and volumetric assessment of a potential reservoir.

Explorer Historical Highlights

To most outsiders in the 1950s, the Buraimi Affair was a passing curiosity, a faraway squabble about territorial rights in a remote corner of southeast Arabia known as the Buraimi Oasis. The British government backed its protégés, Abu Dhabi and Oman, against Saudi Arabia, while the United States government took a mediating role. However, as the Time magazine report suggested, there was another aspect to the dispute: it was rumoured that Buraimi was “floating on a pool of oil.”

“Wait! There is a short cut. Turn right from here”. That’s probably the sound of an electric current bypassing the resistive hydrocarbons, in a maze or network of porous media, when traveling from transmitter to receiver. This workshop will serve the participants need with the up to date advancements in describing and characterizing low resistivity and low contrast pay, and eventually, maximize resources.

Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

VG Abstract

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

DL Abstract

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

DL Abstract

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.
